Personal Area Network Pairing

1. A method for automatically identifying a patient in a healthcare application using a wristband on the patient's body, the method comprising: attaching the wristband to the patient, the wristband adapted to provide out-of-band pairing data of a personal area network of the patient, the out-of-band pairing data including an identifier of a patient monitor device; coupling a first sensor device to the wristband, wherein the first sensor device obtains physiological data of the patient; receiving, by the first sensor device, the out-of-band pairing data provided by the wristband; attaching the first sensor device to the patient's body; detecting, by the first sensor device, the personal area network that uses the out-of-band pairing data; joining, by the first sensor device, the personal area network that uses the out-of-band pairing data; attaching a second sensor device to the patient's body; detecting, by the second sensor device, the out-of-band pairing data injected into patient's body by the first sensor device once the first sensor device is paired with the patient monitor; measuring first physiological data from the patient's body using the first sensor device; measuring second physiological data from the patient's body using the second sensor device; transmitting, by the first sensor device, the first physiological data to the patient monitor device via the personal area network; transmitting, by the second sensor device, the second physiological data to the patient monitor device via the personal area network; correlating, by the patient monitor device, the first and second physiological data of the first and second sensor devices using a correlation factor between the first physiological data and the second physiological data; and determining, by the patient monitor device, whether the first and second sensor devices are associated with the same patient based on said correlation factor of the first and second physiological data.
